AstroJargon: “Cluster Shadows” by the S-Z Effect

Welcome back to the AstroJargon of the whatever-time-frame-I-feel-like series! Here I break down some commonly used terms in astronomy so that the language barrier between scientists and science lovers can be breached. Today I’d like to explain the S-Z Effect, SZE, or Sunyaev-Zel’dovich Effect. I’ve already touched upon this briefly over on Discovery. I wantedContinue reading “AstroJargon: “Cluster Shadows” by the S-Z Effect”

AstroJargon of the Week: Blazar

This week’s… last week’s… aw, did I miss a week? Anyway, THIS week’s “astrojargon” has a super-fun name, and it’s a pretty fun object as well. I’m talking about blazars. This is a subclass of AGN, the jargon with which I started my series. A blazar is highly variable, very luminous, and quite polarized. (PolarizationContinue reading “AstroJargon of the Week: Blazar”

AstroJargon of the Week: HI

For this week’s (late) AstroJargon, I’d like to point out a bit of jargon I used in my Ada Lovelace post the other day. I talked all about HI (the letter “H” and the Roman numeral one) studies, and before posting, I quickly inserted “neutral hydrogen” as a definition. But why is that important anyway?Continue reading “AstroJargon of the Week: HI”

AstroJargon of the Week – AGN

Jeffrey Bennett, astronomer and author, once told us that a typical astronomy textbook has about as many vocabulary words as a typical foreign language textbook. So, in addition to teaching physical and astronomical concepts, we’re teaching a whole new language! Jargon is incredibly useful for making detailed communication within a specific field efficient and convenient,Continue reading “AstroJargon of the Week – AGN”
